I understand your frustration compared to your old pilot. Several things make CX9 have less MPG - heavier (compared weight at least 300lb more) - bigger engine (3.7 vs 3.5) and Honda is good at lean burning - wider tires (245 vs 225/215) - short 1st gear (much shorter than your Pilot - more puppy starting off) - new - it gets better after 10000 miles Mazda designed CX9 to be sporty (zoom-zoom), not king of MPG. My 1st tank was 16.5 mixed driving. CX9 is more efficient on highways due to low drag (0.36) and tall 6th gear. I can easily get 22mpg (with AWD) travelling at 75mph+.   In short, to improve what you get now - ease off at 1st gear - time the lights (a common Prius technique) - pump up your tire pressure to 35+ psi - get rid of junks in your vehicle - use of K&N filter helps a bit in city stop-n-go driving (not highway) - use of synthetic may also help a bit (city and highway)   Vehicles work at the best when warmed (i.e. temp gauge at middle) in term of MPG also. The 1st couple miles are usually very bad since the vehicles need to warm up to operating temp ASAP so that emission control can reach a good state (heat up the CAT converter).   Go read the 2009 Pilot site/forum. They are not exactly getting very good MPG either in city driving. It comes with heavier new vehicles and tighter emission requirement (clean up emission ASAP).   Anyway, not to defend for CX9. CX9 is a great CUV with handling in mind, not super MPG. For the latter, Highlander is probably the best by 2mpg at least. Replies to this message: gabby13 (Jun 01, 2009 7:32 am)
